Definitions

  • the invention relates to a roller glider with the features of the preamble of claims 1 and 10.
  • Such a roller slide is known from EP-A-0 710 495. It has a variety of u. a. Triangularly arranged rollers for supporting the forefoot, which lie on the floor in the unloaded state of the roller glider.
  • This roller glider can not only be used in sports, but can also be used for therapeutic treatment in the event of muscle or bone malformations and in particular posture damage to legs or feet occur. Such damage to the posture of the feet can be attributed, among other things, to insufficient training of the foot muscles.
  • a healthy foot In healthy feet, the body weight is distributed to the foot from the hip joints to the knees and down to the upper ankle. A healthy foot that shows no anatomical deformities absorbs between 50 and 90% of the total load when standing on the heel bone and between 10 and 50% of the total load on the midfoot and forefoot. When walking, the force that is transmitted through the legs to the heel is dynamically distributed on the forefoot. A healthy foot hold v ie by a biodynamic equilibrium, which is produced by the form of the individual foot bones and by muscle pull, per ⁇ manent gc under Belastun 4 e ge.
  • the knee-lowering foot is counteracted in early childhood with foot exercises. These are exercises in the toe and heel walk, gripping exercises and extension exercises in the toe area.
  • This previous kink-lowering foot therapy through physiotherapy exercises usually includes one to several times a week of practicing with a physiotherapist and also daily practice at home.
  • these exercises have the disadvantage that they are not maintained for several years, on the one hand the parents do not have the necessary stamina and on the other hand the children themselves have so little fun with the exercises that a defensive behavior caused thereby further practicing is made impossible.
  • Another therapeutic measure to improve the arch of the foot is the provision of customized insoles. These are usually prescribed by the doctor every six months depending on the state of growth of the foot and support the arch of the foot during the entire growth phase.
  • this therapy is a passive measure and does not promote the muscle growth that is responsible or jointly responsible for the deformity, but on the contrary, it rather creates a relaxation of the muscles, since the arch of the foot is additionally supported by the insoles.
  • roller glider which allows selective loading of individual foot sections, can therefore be used, especially since running with this roller glider on the one hand represents training for the leg and foot muscles and, on the other hand, children are particularly interested in leisure activities enables such a therapy to be maintained over a longer period of time.
  • roller glider in the form of a roller skate is known from DE-B-1 1 17 013.
  • This roller glider is designed to hold a normal shoe. It has a base plate carrying castors on the underside. which consists of two longitudinally adjustable parts made of flexible plastic, namely a front and a rear part. Each section has a projecting flexible sliding member, the two sliding members overlap and can be connected to one another by a clamping screw. A flexible middle section is thus formed between the two sections mentioned.
  • the rollers are each pivotally mounted about a vertical axis on the footplate, with three rollers being evenly triangularly distributed on the front section and only one roller being arranged centrally on the rear section.
  • the present invention is based on the object of designing and developing the known roller glider described at the outset in such a way that when the roller glider is used, individual foot sections can be loaded in such a way that a rolling behavior largely corresponding to the natural movement of the foot is achieved and optimal therapeutic treatment of the Buckling deformity is possible.
  • the object presented above is achieved by a roller glider with the features of claims 1 and 10, respectively. Advantageous further developments can be found in the subclaims.
  • An essential idea of the present invention is to improve the rolling behavior of the roller glider by developing the front sole section and in particular to approximate the natural movement sequence.
  • the proposed arrangement of the front rollers supports a natural bend in the front sole section relative to the other sole sections.
  • the angling of the front sole section in the unloaded state serves the same purpose. In particular, these two measures complement each other.
  • only three front rollers are provided. This has the effect that the rolling resistance is kept to a minimum, so that an almost natural walking or running with the proposed roller glider is possible.
  • a good equilibrium position is obtained in particular in that the front roller defining the tip is arranged in the middle between the two further front rollers and / or in the middle between the rear rollers with respect to the rolling sliding direction of the rolling slide or in the case of vertical rotation of the rollers with respect to the longitudinal extent of the rolling slide .
  • At least one of the front rollers is designed to be rotatable only in the forward direction, while it is designed to be blocking in the other direction. This only allows rolling in the forward direction, but pushing off, i.e. accelerating, is very simple because of the roller blocking that is effective in the reverse direction, so that the forward movement has very similarities to normal forward movement.
  • rollers are integrated into the sole, that is to say partially protrude into recesses in the sole, so that the axes of rotation of the rollers lie essentially in the area formed by the underside of the sole, since a particularly low-build and accordingly tilt-stable roller glider can be realized.
  • a preferred development is characterized in that the rollers are mounted on the sole in such a way that the axes of rotation of the rollers can be adjusted about pivot axes which are essentially perpendicular to the sole.
  • a natural movement sequence is also beneficial if the rear roller is arranged substantially below and shortly before the lower end of the heel bone of the foot to be picked up by the shoe.
  • the rear roller is arranged essentially centrally with respect to the transverse extension of the rear sole section.
  • the rear roller is preferably arranged close behind the anatomical point of contact of the heel or the contact surface of the heel bone. This is additionally or alternatively supported by the fact that the rear rollers of the front sole section are preferably arranged close behind the corresponding anatomical support points of the forefoot to be supported.
  • rear rollers are provided and all are arranged next to one another. In this way, a longitudinal tilting of the rear sole allows the use of the roller glider, whereby a further approximation to the normal rolling behavior of a healthy foot can be achieved.
  • the rear rollers in the rearfoot area can be dynamically provided with a braking effect. This is ensured by the fact that the rear rollers have a rolling resistance which is dependent on the weight load, the rear rollers rolling freely below a weight load threshold and having an increased rolling resistance above this weight load threshold. This means that if the load on the rear foot is too high, there is a braking effect and, on the other hand, free roller sliding is possible if the load on the rear foot is less, for example half the total load. Thus, a load on the forefoot is forced while driving, while avoiding putting on the rear foot in the shoe. This strengthens the arch-stabilizing foot muscles. In particular, the flexors (lower leg flexors, foot flexors) are specifically strengthened.
  • the forefoot When braking, the forefoot must be raised again in order to put more pressure on the rear castors and thus bring about the braking effect. This strengthens the extensors to a special degree.
  • the posture when gliding freely corresponds to the posture when alpine skiing and thus additionally leads to an ideal strengthening of the entire leg and trunk muscles.
  • the roller slide is therefore also suitable as an ideal training instrument for cross-country skiing.
  • the weight loading threshold can furthermore be set in the rear rollers, so that the braking effect can be set as a function of weight and training.
  • roller glider is advantageous in the roller glider according to the invention, since a considerably greater mobility of the foot is thus possible.
  • This also serves to train the foot muscles and thus increases the therapeutic possibilities, since it enables the roller glider to be controlled even more from the foot and not only from the thigh and lower leg muscles.
  • the risk of ankle twisting with this roller glider is low since the rollers have a sliding surface in the area of the contact surface of the forefoot and in the area of the rear foot form a gliding line running transversely to the longitudinal direction and because the center of gravity is low.

  • FIG. 2 shows a schematic side view corresponding to FIG. 1 without a shoe but with the bones of a foot carrying the roller glider
  • Fig. 4a, b, c is a schematic plan view of the roller glider according to FIG. 2, wherein the foot is omitted in the representations b and c, and
  • Fig. 1 shows a side view of an embodiment of a proposed roller glider that has a shoe 1 with a sole 2.
  • three front rollers 3 are arranged so that they form a sliding surface.
  • two rear rollers 4 are arranged in the rear foot area of the sole.
  • the sole 2 has three sections, namely a rigid front sole section 5.
  • the terms “rigid” and “flexible” are of course not to be understood absolutely. One can refer here to the definition of sole rigidity in shoes in general. common fall back.
  • the flexible middle sole section is often formed only by a bending strip directly adjoining the front sole section, so that the angular position between the front and rear sole sections is realized on a relatively short piece of the sole is settled. This is also a common technique for sports shoes. In addition, a correspondingly narrow bending strip also frequently occurs on its own, even if the central sole section is wider overall and flexible overall.
  • the front sole section 5 and the rear sole section 7 are therefore movable relative to one another, since the flexible middle sole section 6 enables the front sole section 5 and the rear sole section 7 to assume different angles with respect to the load on the shoe .
  • the proposed roller glider is designed in such a way that the front sole section 5 in the almost unloaded state, for example when a carrier of the roller glider stands still, is slightly raised by an angle ⁇ toward the front end of the roller glider, as in FIG. 2 shown.
  • This angle ⁇ with respect to the roller sliding surface defined by the rollers 3, 4 or with respect to the running floor for the roller sliding is preferably a maximum of 25 °.
  • This raising of the roller glider in its front area ideally supports the natural rolling behavior of a foot carrying the roller glider.
  • the various sole sections 5, 6 and 7 of the roller glider are now configured as follows.
  • the front sole section 5 is essentially adapted to the contact surface of the forefoot, so that the front sole section 5 fully supports the forefoot.
  • the rear sole section 7 is substantially adapted to the contact surface of the rear foot, so that the rear sole section 7 supports the rear foot.
  • the front sole section 5 forms a flat surface on the underside, into which the front rollers 3 are each partially sunk and distributed such that the front rollers 3 form an essentially triangular sliding surface.
  • the two rear rollers 4 are integrated in the rear sole section 7, which likewise forms a flat surface on the underside.
  • the shape of the flexible middle sole section 6 is adapted to the shapes of the front sole section 5 and the rear sole section 7, so that all sole sections 5, 6 and 7 together form a continuous sole 2 form.
  • the flexible middle sole section 6 is curved upwards so that the middle sole section 6 creates a shape of the entire sole 2 which is adapted to the foot.
  • the middle sole section 6 it is also possible to design the middle sole section 6 as a flat section, so that the lower surfaces of the front sole section 5, the flexible middle sole section 6 and the rear sole section 7 lie essentially in one plane in the unloaded state.
  • FIG 3 shows the sole 2, which has the three sole sections 5, 6 and 7, for different stages of the movement during the roller sliding.
  • FIG 3a shows the sole 2 in the unloaded state or in the state of standing, that is to say in a state in which the front sole section 5 and the rear sole section 7 are equally loaded and thus both via the rear and rear front sections, not shown here Rollers have contact with the ground, the front sole section 5 preferably being slightly raised with its tip.
  • FIG. 3b shows the arrangement of the sole sections 5, 6 and 7 in a state in which only the front sole section 5 is loaded. This state occurs precisely when pushing backwards occurs during rolling sliding.
  • the advantageous effect of the flexible central sole section 6 becomes clear in a special way. Because, like when walking with normal shoes, the rear sole section 7 is raised, while the front sole section 5 is largely in contact with the ground. At the same time, preferably at least one roller in the front sole section 5 is blocked against reverse rotation. This means that roller gliding with the roller glider according to the invention enables a movement sequence similar to that which is the case when walking with normal shoes. Finally, the rear sole section 7 has contact with the ground in the arrangement of the sole sections 5, 6 and 7 shown in FIG. 3c, while the front sole section 5 is raised. This attitude is adopted in particular when braking the roller glider, as will be described in detail below.
  • the rear rollers 4 have a rolling resistance that is dependent on the weight load.
  • the rear rollers 4 can roll freely below a weight load threshold, but they have an increased rolling resistance above the weight load threshold. This forces an even distribution of the weight load on the forefoot and the rear foot during roller gliding.
  • braking devices can also be implemented, for example the brake pads known from normal roller skates at the rear edge of the rear foot area.
  • the distance between the rear rollers 4 and the rear sole section 7 can be changed, the distance being dependent on the weight load.
  • a spring is arranged between the rear rollers 4 and the rear sole section 7, which allows a change in the distance between the rear rollers 4 and the rear sole section 7 depending on the weight load.
  • an elastic element for example a rubber buffer or a buffer made of another elastic material, can also be used at the appropriate point.
  • the distance between the rear rollers 4 and the rear sole section 7 can be adjusted with the aid of an adjusting screw.
  • the weight loading threshold can thus be set in a simple manner, so that the braking properties of the rear rollers 4 can be set depending on the weight and the training condition of the runner to be treated.
  • a weight scale is assigned for this adjustment of the adjusting screw, which enables a reproducible adjustment of the weight loading threshold.
  • roller glider is therefore particularly suitable for the therapeutic treatment of articular deformities.
  • each roller bearing 16 is each in rotational disc-shaped roller bearings 16 held on the underside of the sole 2.
  • these ring-shaped roller bearings 16 are integrated into the sole sections 5 and 7 in such a way that the roller bearings 16 can each be pivoted about axes which run essentially perpendicular to the undersides of the sole sections 5 and 7.
  • each roller bearing 16 carries a roller 3 or 4 with an axis of rotation which is essentially parallel to the undersides mentioned.
  • This adjustability opens up the possibility of compensating for internal or external rotational misalignments in the region of the leg axis, such as the ankle axis, knee joint axis or hip joint axis, by appropriately aligning the rolling sliding direction of the rolling glider with respect to its longitudinal extent.
  • the shoe 1 is designed as a low shoe. Because of the low center of gravity, which is caused by the arrangement of the rollers 3 and 4 in the sole 2, and because of the large sliding surfaces caused by the distribution of the rollers 3 and 4, the risk of buckling during roller sliding is greatly reduced, so that a special ankle support is not necessary.
  • a low shoe When using a low shoe, however, greater mobility of the entire foot is brought about than in the case of a shoe that encompasses the ankle, which in turn accommodates the movement therapy of the foot.
  • the shoe can also be designed such that it extends beyond the ankle in order to support the ankle.
  • roller glider Another essential aspect of the proposed roller glider can be seen in the arrangement of the rollers 3, 4 on the underside of the sole 2 or the respective sole sections 5 and 7. To illustrate this particular arrangement, reference is made in particular to FIGS. 2 and 4 below.
  • the three front rollers 3 are arranged in a triangular distribution on the underside of the sole section 5.
  • the rollers 3, which define the essentially triangular sliding surface 18, are each arranged longitudinally offset from one another. Since in the example shown the axes of rotation of the roller, which are essentially parallel to the underside of the sole, If 3, 4 on or in the sole 2 or the sole sections 5, 7 are preferably aligned parallel to one another, a rolling sliding direction of the rolling glider essentially in the direction of the longitudinal extension of the shoe 1 is fixed, and the three are with respect to this rolling sliding direction front rollers 3 both longitudinally and transversely offset from each other.
  • the substantially triangular or approximately trapezoidal sliding surface 18 is fixed in such a way that the sliding surface 18 forms a tip which is blunted depending on the width of the front roller 3 det. Due to the already mentioned longitudinal misalignment of the front rollers 3, it goes without saying that the triangle 17 formed by the rollers 3 is not mirror-symmetrical with respect to the direction of roll sliding or the longitudinal extent of the roller slide.
  • the already mentioned foremost roller 3, which forms the tip of the triangle 17, is arranged according to the preferred embodiment substantially below the second and third toes 8, 9 of a foot 10 received by the roller glider, and this roller 3 is relatively close to the distal end of the roller the two toes 8 and 9 mentioned and in particular in the area of the second middle toe bone 11 and in the area of the third distal toe bone 12.
  • the foremost roller 3 thus lies essentially in a longitudinal central axis of the shoe 1 or the roller glider.
  • the two other corner points of the triangle 17, the rear front rollers 3, are likewise offset from one another in the direction of the rolling sliding movement direction of the rolling slide, the inner roller 3 being further forward with respect to the rolling sliding direction and the outer roller 3, in contrast, further rear lies.
  • these two rollers 3 define an oblique course of the rear edge of the sliding surface 18 defined by all the front rollers 3 in the plane of the sole with respect to the rolling sliding direction.
  • these two aforementioned rollers 3, arranged on the underside of the sole section 5, are essentially below the first metatarsal head 13 and the fifth metatarsal head 14, that is to say in regions below the distal ends of the first and fifth metatarsal bones of the one in FIG 2 and 4 shoe 1 not shown foot 10 arranged.
  • the inner of these two rollers 3 is located essentially below the ball of foot 10, not shown in the drawing.
  • the good rolling properties are accordingly achieved in the roller glider with the three sole sections 5, 6 and 7 already mentioned in that the front rollers 3 arranged on the front sole section 5 are distributed over the underside of this sole section 5 in such a way that they are arranged one by one Define a substantial triangular or trapezoidal sliding surface 18 with a forwardly pointing tip, the rear edge of the sliding surface 18 running obliquely to the roller sliding direction defined by the rollers 3.4 from the back outside to the front inside.
  • a movement sequence which is particularly pleasant for the user when the proposed roller glider is used is achieved in that the two rear rollers 4 provided in the exemplary embodiment are aligned with their axes of rotation. This ensures that there is no extensive sliding surface on the rear sole section 7, but ideally, in the borderline case, a quasi-linear extension of the contact area defined by the rear rollers 4 between the roller glider and the floor.
  • This by a correspondingly aligned arrangement even with more than two rear rollers 4 or with only one rear roller 4 formation of a quasi uniaxial support leads to an advantage in the rolling sliding direction on the rear sole section 7 to the advantage that the sole section 7 easier around Axis of the rollers 4 is pivotable in the state placed on the floor. This supports a particularly natural movement.
  • Fig. 2 shows that the rear rollers 4 are arranged with their axes of rotation near the rear lower end of the heel bone 15 of the foot 10 and in particular this slightly offset forward. This position has proven to be proven to be particularly advantageous for a high wearing comfort of the roller glider and a movement sequence that is optimal from a therapeutic point of view when using the roller glider.
